750-1491 WAGO Industrial Automation Components

WAGO 750-1491 is an automation part featuring two analog inputs and a total of two channels per module, designed to handle resistor bridge (strain gauge) signal types. It supports signal voltages UD of +/-15mV to +/-360mV and signal voltage Uref of internal +5 V or external +/-5 V to +/-15V, with a 16-bit resolution. The data width includes 4 x 16-bit data and optional 4 x 8-bit control/status, boasting an internal resistance of > 200kΩ (Uref) and > 1.4mΩ (Ud). The conversion time is a minimum of 10ms, with a measurement error at 25°C of UD +/-30 µV and Uref +/-0.05% of the upper-range value, which can be improved to +/-0.05% with user calibration across the entire temperature range. It operates on a 5 VDC supply voltage via data contacts, with a current consumption of 70mA for the system supply and 200mA for system and sensor combined. Isolation per UL 61010-2-201 is 1.2kVDC system/channel and channel/channel, and it features LED indicators for function and error signaling. Connection is facilitated through 16 x Push-in CAGE CLAMP for inputs/outputs, accommodating solid conductors of 0.08...1.5mm2 / 28...16 AWG and fine-stranded conductors of 0.25...1.5mm2 / 22...16 AWG with a strip length of 8...9mm. The part measures 12mm in width, 100mm in height, and 69mm in depth, with a mounting depth from the upper edge of the DIN-rail at 61.8mm, and is designed for DIN-35 rail mounting. The housing is made from polycarbonate and polyamide 6.6, with a fire load of 0.837MJ and a weight of 44.9g. It is CE marked, operates in ambient temperatures of 0...+55°C, and is stored in temperatures ranging from -40...+85°C. The protection type is IP20, with a pollution degree of 2 per IEC 61131-2, and it can operate up to an altitude of 2000m. The mounting position can be horizontal or vertical, with a relative humidity tolerance of 95% without condensation. It is shock resistant to 15g per IEC 60068-2-27, with EMC immunity and emission compliance per EN 61000-6-2 and EN 61000-6-3, respectively, and exposure to pollutants compliance per IEC 60068-2-42 and IEC 60068-2-43. The product is RoHS compliant with exemptions 6(c), 7(a), 7(c)-I, and 7(c)-II, packaged individually in a box, and has a GTIN of 4066966116120 with a customs tariff number of 85389099990.
